Developer blog: "Vividas is the company behind 'Vividas Player' (Suprise!) which is a video streaming platform (powered by VP6/VP7) which is very much like (to dumb things down) quicktime or Windows Media Player for streaming content, only with a twist. Its ultra fast, compact, installation-requiremente-requireded-no and very bandwidth efficient... The decoder - written in C/C++ with a healthy mix of ASM - is around 250-300Kb. Most of the internals is hush hush so I cant reveal much, but what is interesting is the uptake of broadband across the globe and the future prospects of HD-Quality video streaming and where this technology is headed" [1]
Actually the decoder is a 800kb DLL.
The player has support for Speex, Vorbis and VP6.
